dedicated NIC

Jump to solution

Hi @ all. Im new here and hopefully someone can help me with my special problem.

Is it possible running a virtuel machine with physical network-adapter?

Example:

I've a host-system with 2 NIC's.

NIC 1 is in Subnet 1 for network-acces with host

NIC 2 is in Subnet 2 for network-access with guest

Because our Security-Level, the Host-system is allowed only using Subnet 1 and the guest-system is allowed only using Subnet 2

For sure both NIC's are installed on the host-system but only NIC1 is configured on host.

Hi,

im using a vmware-server 2.0.1

Host-System is a Windows Server 2008 Standard

PS: If i need another vmware-version which supports physical access on nic's, i'm able to buy them.

To dedicate a NIC, use the Virtual Network Editor (vmnetcfg.exe) to

disable automatic bridging and then create a bridged network just on

the NIC that you want the guest to use and make sure that this is the

NIC that the guest has assigned to it. Probably also worth taking off

the VMware Bridging Protocol from the NIC that you won't be using. If

both NICs are conencted to the same subnet, I'd also take File and

Print services off the NIC used for bridging and ensure any other

services on the host, e.g. DNS, aren't bound to that NIC either. Not

sure if this is going to solve your problem though - I'd set up host

perfmon logging to see if I could see resource issues when the user's

experienced problems.

ok it seems to run like that:

  • turn off automatic bridging

  • associate an physical network-adapter (NIC2) with a virtual network adapter (vmnet0)

  • configure your virtual machine using the associated virtual network (vmnet0)

  • on physical network adapter (host-system/NIC 2) turn off all services, ipv4 and ipv6 in exception Vmware Bridge Protocol and driver for topology

  • configure virtual network adapter on running virtual machine
